The Bank of Japan's official historical coin table identifies the 1916 issue with a 23.03 mm diameter, 3.75 g nominal weight and a 95/4/1 copper–tin–zinc alloy. The approximately 1 mm thickness is a secondary catalogue specification, not verified against that official table.

03 DESIGN & CONTEXT

Design

Denomination & Arabesque Side

The denomination 一錢 appears within concentric circles, framed by ornamental arabesque and chrysanthemum motifs. Japan's official historical table identifies this as the obverse.

Paulownia & Date Side

A five–seven paulownia emblem is accompanied by cherry blossoms, the national inscription, and the Taishō-era date. Japan's official historical table identifies this as the reverse.

Historical Context

Japan Mint's institutional history records a 1916 reduction in the diameter and weight of the 1 Sen and 5 Rin bronze denominations. This coin carries the reduced-size paulownia bronze design first introduced in Taishō 5 (1916).

Orientation & Artwork Note

Coin-catalogue obverse/reverse conventions are not uniform: the Bank of Japan's official table and Numista apply opposite side labels. Descriptive side names above avoid ambiguity. No third-party coin photograph, logo, valuation chart or catalogue illustration is reproduced on this page.

The reported mintage of 253,210,000 is attributed to Numista, not Japan Mint. Japan Mint history establishes the 1916 redesign of this coin type and its physical-standard change, while the Bank of Japan provides the official type specifications; neither consulted official record directly confirms the year-specific mintage total.
